## Types

### Basic

• [ntypes.Bytes](https://godoc.org/github.com/piotrkowalczuk/ntypes#Bytes)

• [ntypes.String](https://godoc.org/github.com/piotrkowalczuk/ntypes#String)

• [ntypes.Bool](https://godoc.org/github.com/piotrkowalczuk/ntypes#Bool)

• [ntypes.Int32](https://godoc.org/github.com/piotrkowalczuk/ntypes#Int32)

• [ntypes.Int64](https://godoc.org/github.com/piotrkowalczuk/ntypes#Int64)

• [ntypes.Uint32](https://godoc.org/github.com/piotrkowalczuk/ntypes#Uint32)

• [ntypes.Uint64](https://godoc.org/github.com/piotrkowalczuk/ntypes#Uint64)

• [ntypes.Float32](https://godoc.org/github.com/piotrkowalczuk/ntypes#Float32)

• [ntypes.Float64](https://godoc.org/github.com/piotrkowalczuk/ntypes#Float64)

### Arrays

• [ntypes.BytesArray](https://godoc.org/github.com/piotrkowalczuk/ntypes#BytesArray)

• [ntypes.StringArray](https://godoc.org/github.com/piotrkowalczuk/ntypes#StringArray)

• [ntypes.BoolArray](https://godoc.org/github.com/piotrkowalczuk/ntypes#BoolArray)

• [ntypes.Int32Array](https://godoc.org/github.com/piotrkowalczuk/ntypes#Int32Array)

• [ntypes.Int64Array](https://godoc.org/github.com/piotrkowalczuk/ntypes#Int64Array)

• [ntypes.Uint32Array](https://godoc.org/github.com/piotrkowalczuk/ntypes#Uint32Array)

• [ntypes.Uint64Array](https://godoc.org/github.com/piotrkowalczuk/ntypes#Uint64Array)

• [ntypes.Float32Array](https://godoc.org/github.com/piotrkowalczuk/ntypes#Float32Array)

• [ntypes.Float64Array](https://godoc.org/github.com/piotrkowalczuk/ntypes#Float64Array)

Arrays support is not an SQL standard. Extra import needs to be added to make it working with [postgres driver](github.com/lib/pq):

` import _ "github.com/piotrkowalczuk/ntypes/ntypespq" `

## Interfaces

Some type implements set of interfaces:

• [driver.Valuer](https://golang.org/pkg/database/sql/driver/#Valuer) excluding Uint64 and some arrays

• [proto.Message](https://godoc.org/github.com/golang/protobuf/proto#Message)

• [sql.Scanner](https://golang.org/pkg/database/sql/#Scanner) excluding Uint64 and some arrays

• [json.Marshaler](https://golang.org/pkg/encoding/json/#Marshaler)

• [json.Unmarshaler](https://golang.org/pkg/encoding/json/#Unmarshaler)

## Helpers

• [ntypes.True](https://godoc.org/github.com/piotrkowalczuk/ntypes#True)

• [ntypes.False](https://godoc.org/github.com/piotrkowalczuk/ntypes#False)

Besides that each type implementss func <Type>Or(<builtin>) <builtin> {} method. It returns given argument if receiver is not valid or is nil. For example: [ntypes.Bool.BoolOr](https://godoc.org/github.com/piotrkowalczuk/ntypes#Bool.BoolOr).
